• Behavioural differences of IPv6 subnet-router anycast address implementations

  The subnet-router anycast address is a unique IPv6 address that is autoconfigured on a device that is a router (meaning net.ipv6.conf.all.forwarding=1 in Linux context) when the subnet prefix length is shorter than a /127. In theory, when a host on the subnet/local link sends a packet to this address, it reaches the closest router in the subnet from the host; this can mean the host itself if IPv6 forwarding is enabled. This implies the initial leading zero address of an IPv6 subnet (::) is going to be auto-injected into the host’s (router) local routing table as an address of type, anycast. So, for example, if 2001:db8::/64 is your subnet, then 2001:db8:: is the subnet-router anycast address.

  After that, reboot the system. Make sure to enter the BIOS (typically, using the F2, F8, F10, or F12 keys). As someone who cares about low power consumption (reduced carbon footprint), I never thought I'd share this tip: turn off all power management or energy saving options. Typical keywords for this are "ACPI", "APM" or anything that has "power" in its name. This is important to make sure the system is ready to execute all commands at the right time (literally).
